ENGINE POWER PLANT.

Patented Aug. 16,1921.

1916. Serial No. 117,567.

.The engine shown is provided with a fuel and air pro aortioning'device or carbureter 1 from which it draws its charge mixture of air and kerosene'oil for V example or other relatively non-volatile li uid fuel requiring eat for vaporization.

he mixture asses first through th p tube 2 around an elbow 3 and through a starting vaporizer tube 4 f directly into the e or casing for the as a heater, may serve as heat the tube 4. n the casein hand, the normal vaporizer is constituted by der engine directly and closely opposed to. all of the exhaust ports, butthe invention is not confined to any particular type of engine or engine Vaporizer whether that be of the enturi tube-or other type, or whether in- .normal running as in-the present case or a both conditionsi. The burner head comprises a nozzle cap 10 connected with the flame tube 8 by an annular air inlet chamber 11 and with the mounted in the cap and in aspirating relafluid pressure or air nozzle 1 1, so that the atomized fuel spray therefrom asses axially through the air chamber 11,

the opposed terminals of a pair dugs 15 just before it joins the air from said chamber. A spark between these terminals ignites the spray and air admitted through the air chamber 11 co1 1- tinues and completes the combustion within the closed passage. The air reaches the air inlet through a pipe '16 and a star-shaped mem 17 is placed at about the of this air with the ignited. spray 15 for directing and assisting the combustion.

art constituting t No. 1,231,152, and although this type is preferred, other types of inclosed heaters may be employed in ,its place. In the present case, the burner head is applied to an elbow or angle of the flame tube 8, so that the flame impinges on the interior elbow 3 and is thus subject to change of direction immediately on emerging from the head. eferring more particularly to Figs. 1 to 3, atomizing air or fluid for the nozzle 14: is supplied through pipe 18 from a smal blower or rotary air pump 19 and the combustion supporting air is supplied through pipe 16 from a rotary fan blower 20 and both blowers are. geared together and driven by a small high speed electric motor 21, the former to provide a relatively high atomizing pressure and the latter a considerable volume of air at a somewhat lower pressure. The blower 20 is directly mounted on the motor shaft and the smaller blower 19 is driven therefrom through a worm and worm gear connection 22 as clearly illustrated in Figs. 1 and 2. The relative air deliveries from the two blowers are predetermined so that the spark will ignite the spray and the flame will be continued to complete combustion under high .velocity within the easing 8, and at such pressure as will suflice to overcome the resistance of the oflt'take 9 and at the same time consume and convert into heat an adequate amount of the fuel. this purpose th spray produced by the atomizing nozzles 12 and 14 (Fig. 1) is relatively rich, that is to say richer .in fuel than would produce complete combustion without the addition of more air from the pipe 16. Such a rich mixture is nonexplosive but is spark-ignitible and by so ignitingiit combustion is established in the flame passage of a continuous and nonexplosive character. Thus the spark gap is located in a nonexplosive portion air which is formed within the burner head- 7 and flame passage. The spark plugs are connected in a circuit 23 to an induction coil 24 the primary 25 of which is subject to S mechanical interruption by the rotary interare entirely i the switch 28 1 vaporizer 2, and

For

f th mixture of fuel and rupter 26 mounted on the worm shaft 22, and all of these parts are compactly mounted together on a base screwed to the engine casting. The motor 21 is .connected to a source of stored energy, represented by the storage battery 7, and a switch 28 is adapted to put it in operation, which results in the immediate establishment of a. flame of high temperature passing through the flame tube 8 as will now be ,understood. The combustion engine is equipped with a starting motor 30 connected by the circuit 31 to the same storage battery 27 and adapted to be set in action by closing the switch 32 adjacent to the switch 28. Starting motors of this kind familiar to the art and therefore the detail thereof is omitted from the drawings. It will be observed that by first closing the vaporizer 4: can be heated to such extent as required for producing the initial vaporization and thereupon the switch 32 is closed to actuate the engineturning motor 30 to put the engine in operation, the switch 28. being kept closed and the burner in operation until after the ex-' hau'st gas from the engine has established the appropriate temperature at the normal which may require several seconds, or even minutes, depending on the heating apparatus and fuel. The engine is surely put in its normal combustion process, by this overla of the burners period and this result is o tained by driving the burner operating members by a motor entirely in dependent of the engine-turning-motor 30 although driven by energy from the same source. .It is of course, also possible to continue the heating of the tube Lfor as long as the circumstances of low volatility of fuel or external temperature may require, or to resume the operation of the burner, after aninterruption, to assist the'combustion process in the engine.

Asa precaution against escape of flame or of very hot exhaust products from the pipe 9, a portion of the combustion supporting air from the blower 20 is shunted across through apipe 33 to said offtake near its 'unction with the flame tube 8, and the air so entering either cools the exhaust products or su plies the oxygen necessary to consume immediately any remaining unconsumed or still burning fuel. This feature is of course susceptible of use in connection with inclosed flame burners generally.

In Figs. 4 to 6, the general construction of the engine, its vaporlzing means, burner head and appurtenant parts will be recogrepetition. In this form the electric motor 10 is direct connected tothe fan blower 20 and the latter is geared by a speed multiplying train to a second stage, fan blower 11, which receives its air from the outlet air pipe 16 of i the blower 20 already at some pressure. This connection 130 cuit 52 short circuits the W and appropriate time interval sure 1n the dellvery pipe 18 WhlCll is thus d thexsaid disk controls the cirh the engine-turning motor 30 and the burner-operating motor 40 in a definlte sequence. It carries a contact plate 47 on its face which is engaged by the brush 48, the plate and brush being terminals of the circuit 49 of the engine-turning motor, and appropriately insulated for the purpose. e edge of the disk 46 is formed with a cam recess 50 controlling the depression of the spring-actuated circuit closer 51 of a cirwhich controls the motor 40 and main, control button 53. lthout tracing the circuits in detail, it will be apparent that bypressing the button 53 t e current from thestorage battery 27 will be closed to the motor 40 and the spark coil 24, thereby operating the blowers 20 and 41 and the igniter and thus actuatin worm gears 42 and 44 and-the cam disk 46,

clrc'uit will remain closed,

complete revolution and its cam recess 50 hasa ain registered with the circuitcloser 51. Eccording to the character of the engine and burner this period of motor operthe disk 46. The b thus operated for one minute regardless of Ffrom the starting of the burner and as y the angular relation of they contact plate, the closure of the circuit 49 is determined by the arcuate leiigth of the contact plate 47 and is of course'suflicient to see the engine well under r its combustion process. After the plate 47 he armature shaft erated by the determined has parted from the brush 48-opening the circuit 49 and stopping the engine-turning motor, the closer 51 still remains closed thereby continuing the operation of the burner operating for a further interval and until the cam disk, 46 has completed its rotation. Thereby the heat of the burner is available to maintain engine ing on the non-volatile claim: 1 The combination with an internal com- 1. bustion engine, of a an inclosed flame b has started its combustionlcycle.
